Failure forms and solutions of rubber O-rings

<p><br></p><p>As we all know, the use of rubber O-rings is very extensive, and plays a very important role in various industries. Therefore, the failure of the O-ring will cause a lot of accidents and will bring great losses to the user. Next, let's take a look at the failure forms of rubber O-rings and their solutions, hoping to help everyone. <a href="dshseals.com" rel="noopener noreferrer" target="_blank"><strong>hydraulic seal manufacturer</strong></a> recommends.</p><p><br></p><p>Method / step</p><p>Form of failure one, installation damage: that is, the seal partly or completely presents a neat wound.</p><p><br></p><p>Reasons: sharp edges and corners, no chamfers; seal size is not correct; seal hardness or elasticity is too low</p><p><br></p><p>Solution: sharp edges and corners, no  chamfer; seal size is not correct; seal hardness or elasticity is too low</p><p><br></p><p>Form two of failure, the seal is curled.</p><p><br></p><p>Reasons: Installation caused; the movement speed is too low; the material is too hard or the elasticity is too low; uneven surface treatment of the O-ring; uneven groove size; rough groove surface and insufficient lubrication</p><p><br></p><p>Solution: correct installation; choose high elastic material; choose self-lubricating material; proper groove design and achieve required processing accuracy; try to use support ring</p><p><br></p><p>Form three of failure, excessive compression: The surface of the seal is deformed in plane and may be accompanied by cracks.</p><p><br></p><p>Reason: the design is not reasonable; the deformation of the material due to heat or chemical media is not considered; the pressure is caused by the excessive pressure</p><p><br></p><p>Solution: The groove design considers the deformation of the material due to heat or chemical media</p><p><br></p><p>Form 4 of failure, extrusion: The seal has a rough, ragged edge, usually on the low pressure side</p><p><br></p><p>Reasons: Too large clearance; Too low hardness or elasticity of seal; Too small groove space; Irregular gap size;</p><p><br></p><p>Corners are too sharp; seals are not the right size</p><p><br></p><p>Solution: reduce the gap size; choose a seal with better elasticity and higher hardness; reasonable groove design; choose a suitable size seal</p><p><br></p><p>5</p><p>Form of failure 5. Chemical corrosion: Chemical corrosion can cause defects such as foaming, cracking, small holes, and discoloration.</p><p><br></p><p>Knowing its physical properties</p><p><br></p><p>Reason: the material does not match the medium or the temperature is too high</p><p><br></p><p>Solution: Choose materials that are more resistant to chemical media</p>
